How to improve the effect of drying equipment in organic fertilizer equipment?

The drying effect of organic fertilizer equipment is not only related to the quality of the machine itself, but also related to the layout of the plant and the daily maintenance of the equipment. The specific layout is as follows:

Feed bin: In order to prevent wet and viscous materials from clogging the feed bin, a reasonable feed bin structure should be designed, such as: asymmetric geometric hopper; Or increase the tilt Angle between the hopper wall and the outlet; Add activation cone or pressure reducing plate in the bin; Or set up a poke hole at the exit. At the same time, it can also reduce the material in the silo, reduce the pressure of the silo, and prevent the phenomenon of clogging. According to the nature of the material can also be designed to break arch discharge vibration feed hopper, used for dryer charging.

Combustion chamber: The form of the combustion chamber should be selected according to the nature and source of the fuel, the form of the dryer, and other factory conditions. For example, the factory has pulverized coal, you can consider the use of pulverized coal combustion chamber; For inferior coal, fluidized furnace can be used.

Secondly, the combustion chamber of the dryer equipment in the organic fertilizer production line generally considers setting up an "air-flue gas" mixing chamber, installing a thermometer to measure the flue gas temperature and a cold air door to adjust the smoke volume. Cold air mixing. It is also necessary to design a properly designed windshield to prevent high temperature flame from burning into the drying cylinder and feed pipe. The feed pipe is covered with heat-resistant concrete or brick chute. In addition, reducing the leakage of cold air in the feed pipe is conducive to improving the drying efficiency.

Drying thermal system: The drying thermal system includes three parts: combustion chamber, dryer, exhaust dust collection: the selection of exhaust fan and dust collector should meet the requirements of the combustion air coefficient of the dryer is not greater than 100 ° C. Greater than 1, 2; The wind speed of the cooling end in the dryer condition is not more than 3m/s; The discharge port under the suction hood shall be provided with an air locking device; The dust collector and exhaust pipe shall have heat preservation and heat insulation measures.
